Yes. I put in booster pads in every time I change.  Depending on what brand you use will differ on how much gets absorbed before it starts totally leaking in the diaper.  Some brands now these day can hold a lot.  There are times where I know the pad is full.  I just find a restroom and pull it out and toss it in the trash and use the rest of the diaper up until I get home.  Even when I am home, I will pull the pad out.  Doing this extends the life of the diaper a bit longer so less changes.
